1 Claim, 7 Drawing Figures .Animportant object of the present inventionis to I provide a containerthe contents of which can be easily removedfrom the inner case by pressing and pushing the top of the quadrilateralhollow three-dimensional body at the right end of the inner case and bytaking the inner case out of the outer case.

Another object of the present invention is to provide a container whichis capable of holding rather long and fragile articles such as ampulesfor injection and safely retaining them without allowing them to comeinto contact with each other and break.

Still another object of the present invention is to pro vide a containerwhich is 'capableof displaying its contents in shop windows when itsinner case is allowed to be partially removed from the outer case.

Still a further object of the present invention isto provide a containerwhich is capable of being manufactured by machinery on a mass productionbasis with-a marked decrease in the number of cumbersome pastingprocesses in assembling it.

In order to make containers for holding long and fragile articles suchas ampules, it has hitherto been necessary for one toprovide the body ofa case with no top, to provide a partition therein for insertion of thecontents and to providea lid on the top. In making such containers,various delicate operations such as pasting the body and the lid, theformation of the body and of the partition, and the insertion andadjustment of those things are required. Thus, they are unsuitable formass production by machinery.

What is more, such containers have a complicated construction and arevery expensive. Besides, it has a further defect in that it is difficultto insert or withdraw such contents as ampules.

On the other hand, the containers of the present invention are not onlysuitable for mass production at low cost in simple mechanicalmanufacturing processes, but are also capable of safely retainingfragile and long articles.

The present invention will now be described in detail by way ofexamplewith reference to the accompanying drawings in which:

FIG. 1 is a perspective view of the container as a whole.

FIG. 2 is a perspective view of the inner case. The letter A indicates abasic type and B a variation thereof.

FIG. 7 is an expansion view of the outer case.

Referring now to the drawings and specifically to FIGS. 1,2,5 and 6 theletter X designates an inner case. Outer front and back walls 3 and 3'are integrally connected at fold lines 2 and 2' on the front and back ofthe base plate 1 of the said inner case X to the base' plate 1. Innerfront and back walls and 5, which are slightly narrower than the outerfront and back walls, are integrallyconnected-at fold lines 4 and 4 tothe outer front and back walls. In the middle of the. edges of the innerfront and back walls 5 and 5 are provided slits 6 and 6', which aretwice as high as the thickness of the material for the inner case. Aleft side wall 8 is integrally connected at a fold line 7 to the leftedge of the base plate 1. There is also integrally formed a slantingleft side wall 13 having any number of cut-off portions 11 and 12fo rpartition having fold lines 11 and 12. Side wall 13 is made slightlynarrower than the width of the base plate 1 by allowing both side edges10 and 10 of the wall 13 to be cut off from a fold line 9.

.An inner case left portion fixing wall 15 is integrally connected tothe edge of the slanting left side wall 13 at a fold line 14, the wall15 being approximately as wide as the base plate 1. A right side wall 17is inte-' grally connected to the right end of the base plate 1"at afold line 16. To the right side wall 17 are integrally connecteda lid 21and an inner lid 22 in turn, the widths of which are made narrower thanthat of the base plate 1 by allowing their both side edges 20 and 20 tobe cut at fold lines 18 and 19in turn.

Extending through said lid 21 to said inner lid 22 are provided foldlines 23' and 24 which form cut-off portions 23 and 24 corresponding innumber to the number of cut-off portions 11 and 12 of the slanting leftside wall 13. To the right edge of the inner lid 22 is integrallyconnected an inner case lid fixing wall 26 at a fold line 25, the wall26 being approximately as wide as the base plate 1. j

The assembling of the inner case is just as has been described above.The outer front and back walls 3 and 3' are allowed to rise and bend atthe fold lines 2 and 2. The fold lines 7, 9, and 14 are bent and thenthe lugs 27 and 27' of an inner case left portion fixing wall 15 areinserted into and fixed in the slits 6 and 6' cut in the inner front andback walls 5 and 5' folded along the inside of the outerfront and backwalls'3 and 3' at the fold lines 4 and 4'. Similarly, the fold lines 18,19 and 25 are folded to form-a quadrilateral hollow threedimensionalbody, and then lugs 28 and 28' on both sides of an' inner case lidfixing wall 26 are inserted into and fixed in said slits 6 and 6 to formthe inner case X with its topopen.

29, and a pasting portion 31 of front and back walls is pasted; and theright side is opened while the remaining five sides are closed to form,the outer case Y. Then, theinner case X is slidably inserted into theouter case Y.

Since any desiredn'umber of cut-off portions 11 and l2, and 23 and 24are provided at corresponding locations on'the slanting left side wall13, and the lid 21 and the inner lid 22; the contents such as a pair ofinjection bottles or of ink eraser bottles, as shown .in FIG. 3, willnot be damaged by colliding with each other in transit.

In opening the lid, just push and press the lid 21 appearing in anarched shape under the cut-off portion 30 at the right edge of the upperwall 29 of the outer case X, as shown in FIG. 1, with'a finger until itbecomes more or less flat, and slide the inner case X out of the outercase Y. Thus, the contents can be removed by a simple oprations.

Although the inner case X has a very complicated construction whencompleted, it can be made from a single sheet of cardboard by onestamping-out operation with a mold blade, and can be assembledthreedimensionally by folding the resulting fold lines without thenecessity of pasting any single area. The inner cases are suitable formass production, and can be produced inexpensively, and so the effectsof the invention is remarkable.

The shape and number of the cut-off portions 11 and 12, 23 and 24provided in the slanting left side wall 13 and the lid 21 and the innerlid 22 may be designed and made according to the type and shape of thecontents.

A second embodiment is shown in FIGS, 3B, B, and 68. An outer case Y isthe same as the outer case Y described above. An inner case Z is of asimplified construction relative to the inner case X described in Ex-'ample l. The numberal 50 indicates a base plate. The numerals 51 and 51indicate front and back walls respectively. They are integrallyconnected to the back grally connected to the right edge of the baseplate 50 at a fold line 58. The numeral 59 indicates a lid, which isintegrally connected to the right edge of the right side wall 57 at afold line 60. The numeral 61 indicates an inner lid, which is integrallyconnectedto the right edge of the lid 59 at a fold line 62. The numeral63 indicates a pasting wall, which is integrally connected to the rightedge of the inner lid 61 at a fold line 64 and is pasted to the baseplate 50. The right side wall 57, the lid 59, the inner lid 61 and apart of the base plate 50 form a quadrilateral hollow three-dimensionalbody. The nume rals 65 and 65 indicate folding walls, which areintegrally connected to the left edges of the front and back walls 51and 51' at fold lines 66 and 66' respectively. The container isassembled as follows. The front and back walls 51 and 51', the foldingwalls 65 and 65, and the left side wall 53 of the inner case 2 arerespectively folded at their respective fold lines 52 and 52, 66 and 66,and 54 so that they are respectively more or less at right angles to thebase plate 50, and the folding wall 55 is folded at'the folding line 56at right angles to the left sidewall 53, and then the inner case Z isinserted into the outer case Y from the left side wall 53.

ln opening the lid of this container, just push and press the top of thequadrilateral hollow threedimensional body of the inner case Z appearedunder the cut-off portion 30 of the outer case Y with a finger until itbecomes more or less flat, and slide the inner case Z out of the outercase Y. Thus, the contents can be taken out or displayed by such simpleoperations.
